Spatial patterns of road kills: a case study in southern Portugal
Universidade de Évora
One major human agent of habitat fragmentation is the ever increasing and expanding road network world wide (Forman et al. 2002), which can be harmful to various faunal groups such as invertebrates (e.g.: Haskell 2001), amphibians (e.g.: Carr and Fahrig 2001), reptiles (e.g.: Gibbs and Shriver 2002), birds (e.g.: Kuitunen et al. 1998) or mammals (e.g.: Philcox et al. 1999). Roads and traffic can act as barriers which may difficult animal movements and reduce population connectivity. By diminishing the gene flow and disrupting sink-source population dynamics, roads may increase inbreeding and loss of genetic diversity (Ferreras 2001).
